Could be waterpump or belt slipping not spinning pump fast enough. I suspect belt is slipping.

How do i know if my water pump is bad on a G6


Disconnect the top radiator hose at the radiator, plug the hole in the radiator where the hose attaches, and put a garden hose in the radiator to keep it full of water.
Start the engine, and if the water pump is working, the water & coolant will pour out of the top hose.
Remember, the thermostat must already be open, or it will not flow until the thermostat gets hot enough to open.
(Or, if the pump is leaking whilst the car is running, or if the pump is "screaming" whilst the engine is running.)

Is it possible the replacement engine has a water pump that turns the opposite direction from the original ?
The thermostat has to be open to allow flow thru the radiator, have you tried running without a thermostat to check flow ?

There are 3 hoses coming from the surge unit. The 2 on the right are clamped and connect to something. The one on the left coming directly behind the cap does not have a clamp on it and it doesn't connect...

Coolant does not seem to be circulating in radiator(94 z28 camaro). The radiator is brand new and it seems not to flow even without the thermastat on. I hate to think it is the water pump again, since the...


Remove the thermostat and run the car. Without the thermostat you should see FULL flow thru the radiator. You can pull the top radiator hose WHERE IT ATTACHES TO THE RADIATOR and start the engine with a garden hose stuck in the filler opening. Don't turn the hose on so hard that it blows water out the radiator hose. You want to water pump to shoot water out the disconnected hose, not the garden hose. A hose COULD be blocked, but it would have to be a pretty big blockage to cut off all flow. Not likely in my opinion. You could take them off and look in them and the heater hoses too. You can blow compressed air thru the heater core to see if it is blocked. As for it being the water pump...they rarely break so bad they won't pump water. Usually the seal goes bad and they leak water out the shaft. Look around, I kinda think you have a bad thermostat. Stuck closed. Drop it in boiling water and see if it opens. You didn't say what engine is in the Camaro, but most of them have a small bypass hose on the top of the water pump running to the intake manifold. Pull it off and see if water sprays out when the engine is running.

99 GrandAm GT v6 3.4L overheating


Can't give you a definite "fix" only because I'd need to do testing. But, two items you need to have checked are: 1. have a hydrocarbon test done fro the cooling system to verify that you do or don't have a head gasket problem. 2. have someone check the radiator with a "heat gun" to see if there are any cold spots. Home flush kits and sometimes even shop flush equipment will force cleaner around, not through heavily plugged areas and not clear the obstruction. Heat gun is best way of finding cold areas that are not flowing.
also...you mentioned fan relays...does the fan come on?

Engine overheating


The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
